The Billboard 200:

Trey Songz nabbed his first No. 1 album on the Billboard 200 chart this week with "Chapter V," as the singer's fifth studio set bowed with 135,000 sold according to Nielsen SoundScan. It was one of four debuts in the top 10, which also saw entries from DJ Khaled, Owl City and Tenth Avenue North.

But now, let's take a look at some of the other movers and shakers on the Billboard 200 and elsewhere on our album charts:

-- Kelly Clarkson: The singer's "Stronger" jumps 35-19 on the Billboard 200, with 15,000 sold -- a handsome gain of 44% compared to its previous week's sales. The title earns its best sales week and highest rank on the chart since April thanks to sale pricing at Target for $6.99 while also got in on the discount action.

The latter retailer's web site promoted "Stronger's" physical CD as a one-day only deal for $4.99 on Aug. 20 -- including free shipping. In terms of CD purchases made via Internet, the album had a 442% gain -- moving from less than 1,000 copies to nearly 3,000 last week.

That's a huge sales figure for such an old title, and marks its best sales week in terms of physical Internet sales since the week ending Dec. 18, 2011 (just under 3,000).

Lately, retailers Best Buy and Target have been marking down select physical CDs to a consumer cost of anywhere between $3.99 to $6.99. Last week, Best Buy priced and promoted Karmin's "Hello" and Lionel Richie's "Tuskegee" for $5.99 and catalog sets from No Doubt, Bob Seger and Dave Matthews Band (among others) for $3.99. Over at Target, it sold Maroon 5's "Overexposed" and Drake's "Take Care" for $6.99. The week previous, Best Buy had everything from Nicki Minaj's "Pink Friday: Roman Reloaded" to Justin Bieber's "Believe" marked down to $5.99.

-- Train: Two of the band's albums on the chart earn gains after their "Today" show performance on Aug. 24. "California 37" motors from No. 44 to No. 32 with a 42% sales increase while "Save Me, San Francisco" re-enters at No. 158 (up 44%).

-- Kiss:

As physical stock of the remastered reissue of "Destroyer" arrived to retail last week, the set bounds back onto the list at No. 58 with 7,000 (up 629%). It briefly returned to the tally dated Aug. 18 (No. 138) when the digital reissue launched. Vintage vinyl fans turned out too, as the album debuts at No. 1 on the Vinyl Albums chart with 1,000 sold.

-- The Darkness: Returning for the first time since December 2005, the band's new "Fragrant World" arrives at No. 44 with 9,000 sold. The set beats the peak of its last offering "One Way Ticket to Hell. . .And Back" (No. 58) but not its sales start (26,000)

-- Chris Tomlin:
His "And If Our God Is For Us. . ." album re-enters the chart (No. 68) for the third time this year, as a $5 discount at Lifeway prompts its 375% gain. It also returned for one-week stays on May 26 and Aug. 4 after limited-time promotions.

-- Tyga: Best Buy lifts "Carless World: Rise of the Last King" by 13% (77-69) after the retailer offered it for $5.99 last week. With just over 6,000 sold, it is the album's best sales frame since June 2.

-- Yellowcard: The band's "Southern Air" drops from No. 10 to No. 89 in its second week -- a fall of 79 positions. It's the fourth-largest fall out of the top 10 so far in 2012. The biggest goes to Bee Gees' "Number Ones," which dropped 190 slots from No. 5 to No. 195 after it had a one-week run in the top 10 after Amazon MP3 sold the set for 99-cents. In fact, that Bee Gees fall is the largest positional decrease since the chart began using SoundScan data in 1991.

-- Pink Floyd:
Amazon MP3's deals of the day dot the chart as usual this week. $3.99 discounts spur gains for Pink Floyd's "Wish You Were Here" (a re-entry at No. 112; up 98%), as well as Tom Petty and the Heartbreakers' "Greatest Hits" (129-50; up 114%), Elton John's "Rocket Man: Number Ones" (81-59; up 36%) and Stevie Wonder's "The Definitive Collection" (a re-entry at No. 72; up 190%).

-- Sublime: Included as part of iTunes' back to school promotion, the band's self-titled release (158-137) was advertised for $7.99 last week, helping its overall 10% increase. In terms of downloads, it was up by 42%.
